One common theme is power play. Often in these fanfictions, the one doing the seducing is using it as a means to gain power over the other character. For example, they might want to get access to secret jutsu or gain influence in the ninja village. Another theme is the exploration of hidden desires. The characters in 'Naruto' have so many repressed emotions and desires, and the seduction scenario can bring these to the surface. It makes for some really intense and emotional reading.
Love and friendship are common themes. Usually, Naruto forms a deep connection with that special someone, which often starts as friendship and then blossoms into love. For example, in many fanfics, Naruto's loyalty and kindness attract the special person.
Power and its implications are also common. If Harry has a new identity, it usually comes with different powers or limitations. Writers explore how he uses or struggles with these new powers. In some fictions, he may have to hide his powers to avoid danger, while in others, he uses them to change the wizarding world for the better.
One common theme is character relationships. For example, exploring the deepening friendship between Naruto and Sasuke, or Naruto's romantic relationships with characters like Hinata. Another theme is the expansion of the ninja world. Writers might create new villages, new ninja clans, or new jutsu. Also, the idea of alternate universes is popular, where the events in the original 'Naruto' series take a different turn.
One common theme is alternate universes. Writers often like to create scenarios where Naruto and his friends are in a different world altogether, like a modern - day setting or a fantasy world other than the ninja world. This allows for a fresh take on the characters.
In such fanfictions, a frequent theme is acceptance. Naruto has to deal with the fact that he's related to the Kyuubi in a special way. This could lead to him facing both acceptance and rejection from his friends and the village. Additionally, the exploration of the Kyuubi's character from a different perspective, not just as a beast but as a 'brother' figure, is common. It can add depth to the overall Naruto world in the fanfiction.
One common theme is her family dynamics. Since she's part of the Hyuga clan, the relationship with her family members, especially her father, can be a big part of the story. It could be about her trying to prove herself to him.
One common theme is the passing of the torch. Older Naruto is often shown mentoring the younger generation, like how Kakashi mentored him. Another theme is dealing with the scars of past battles, both physical and mental.
One common theme is the exploration of their self - discovery. Since they are the same person in a sense, they can see different aspects of themselves. For example, one Naruto might be more confident while the other is more reserved, and they learn from each other.
Teamwork is also a big theme. Despite being the same person in essence, the two Narutos often have to learn to work together. This can be challenging as they may have different personalities due to their different experiences. For example, one Naruto might be more cautious while the other is more impulsive. And the theme of friendship also plays a role, as they are, in a way, their own best friends in these stories.
Another theme is self - discovery. As Naruto faces his dark side, he often learns more about his true nature, his powers, and his place in the ninja world. It's like a journey of self - exploration but with a dark and dangerous twist.
